(The value of .Dv NAME_MAX depends on the underlying file system.) .It Contains a directory component that is not searchable. .El .Pp It is not considered an error if a .Ar pathname argument contains a nonexistent component as long as a component by that name could be created. .Pp The options are as follows: .Bl -tag -width indent .It Fl p Perform portability checks on the specified .Ar pathname arguments. Diagnostic messages will be written for each argument that: .Bl -bullet .It Is longer than .Dv _POSIX_PATH_MAX .Pq 255 bytes. .It Contains a component longer than .Dv _POSIX_NAME_MAX .Pq 14 bytes. .It Contains any character not in the portable filename character set (that is, alphanumeric characters, .Ql \&. , .Ql \&- and .Ql _ ) . No component may start with the hyphen .Pq Ql \&- character. .El .El .Sh EXAMPLES Check whether the names of files in the current directory are portable to other .Tn POSIX systems: .Pp .Dl "find . -print | xargs pathchk -p" .Sh DIAGNOSTICS .Ex -std .Sh SEE ALSO .Xr getconf 1 , .Xr pathconf 2 , .Xr stat 2 .Sh STANDARDS The .Nm utility conforms to .St -p1003.1-2001 . .Sh HISTORY A .Nm utility appeared in .Fx 5.0 .
